Billed Wrong?

I received $7640 in financial aid ((instate scholarship, Pell Grant, university grant, and direct subsidized loan) for the Spring semester. I ended up paying out of pocket about $50. Today, I received an email from the university saying that I am supposed to pay $2821. I reviewed my Financial Aid information and everything is there. However, in my billing statement, everything is there except for the loan.

What should I do?

Call them. Likely loan has come in yet. Find out why not.

^Did you complete Counseling or sign the Master Promissory Note?

Yes.
